Plessey Enables Native Blue and Green Emission on a Single Wafer

Plessey announced that it has successfully achieved native blue and green color emission on the same epitaxy wafer with its GaN-on-Silicon process. (Image: Plessey) To form RGB Micro LED displays, typical approaches are to use a pick and place process to transfer discrete R, G and B pixels or to use Native Blue LEDs as the light source for subsequent color conversion, to Red and Green. But the tiny chip size makes the placement process and conversion very difficult. Plessey’s latest patented growth approach simplifies the color conversion process by c...
